Like the interior, the exterior of the XF-R doesn't do much to tell people that what you're driving is a premium performer. Get closer to it, though, and the slight differences become more apparent. There are the wider rear wheels and arches to match, the front grill that's been revised to accommodate two wide air inlets, new side skirts for better airflow, shiny quad-exhaust tips, and a new hood with a bulge and air scoops for the supercharger. For some it may not be enough, but if you plan on using all that power, a subdued look may be just what you need.
